The HISPEC-DESPEC collaboration, part of the NUSTAR (NUclear STructure, Astrophysics and Reactions) FAIR pillar, aims at studying exotic nuclear structure phenomena with high-resolution in-flight spectroscopy (HISPEC) and stopped-beam experiments (DESPEC).
In recent years, the experimental activity of the collaboration has been focussed on decay studies, where secondary beams produced in...

The nuclear two-photon or double-gamma (2γ) decay is a second-order electromagnetic decay process whereby a nucleus in an excited state emits two gamma rays simultaneously. Compared to first-order decay pathways, such as single photon emission or internal conversion, the two-photon decay branch is very small. Ideal cases for this search are 0$^+$ → 0$^+$ transitions, where single photon...

The evolution of nucleon orbitals and arising nuclear properties moving away from the well-established magic numbers are important questions in nuclear structure. Doubly-magic nuclei beyond the classic shell model have been demonstrated at N=32 and N=34 in calcium (Z=20), however evidence for the persistence of these magic neutron numbers beyond calcium remains somewhat elusive. We are...

The neutron-rich rare-earth isotopes pose a challenge for both experimentalists trying to produce and measure them, as well as for the theorists trying to describe them due to their large valence spaces. Towards the double mid-shell at $Z=66$ and $N=104$, we find some of the most well-deformed isotopes between the $^{132}$Sn and $^{208}$Pb shell closures, as evidenced by their low $2^+$...

The $\nu11/2^{-}[505]$ orbital that extends from below the $N = 82$ shell-closure, dubbed the ``flying fish'', has been described as pivotal in contributing to the deformation in the neutron-rich rare-earth nuclei [1]. The flying fish leaps up towards the Fermi surface with increasing deformation and neutron number and then flops back into the Fermi sea as the neutron number further...
